经香蕉皮粉末处理的硫酸铜溶液对蚕豆根尖微核率的影响

Effect of Copper Sulfate Solution Treated by Banana Peel Powder on Micronucleus Rate of Vicia faba Root Tip Cells

利用香蕉皮粉末处理硫酸铜溶液,研究其对蚕豆根尖微核率的影响。结果表明:随着硫酸铜浓度的增加会导致蚕豆根尖细胞微核率增加,当硫酸铜浓度为200 mg.L-1时,与对照相比微核率达到极显著水平。而加入香蕉皮粉末进行吸附可以显著降低硫酸铜诱发的蚕豆根尖细胞微核率,LSD分析的结果表明,当加入香蕉皮粉末15 g.L-1时,与对照组相比微核率已无显著差异。说明香蕉皮有吸附铜离子的功能,可以抑制铜离子对蚕豆的遗传毒理作用。

Using banana peel powder processing copper sulphate solution to study the effect on micronucleus rate of Vicia fabaroot tip cells.The results showed that：the increasing concentration of copper sulfate could result in micronucleus rate of Vicia faba root tip cells increased,when the copper sulfate concentration of 200 mg·L-1,micronucleus rate difference achieved extremely significant compared with the control.To join the banana peel powder copper sulfate adsorption could significantly reduce the broad bean root tip cells induced micronuclei,LSD analysis showed that when adding banana peel powder 15 g·L-1,micronucleus rate had no significant difference compared with the control.It described that banana peel had the function of copper ion adsorption and could inhibit copper ion bean genetic toxicological effects.
